Questions 1 and 2 below refer to a consumer Who has utility function U(.'I31,.'I32) = V1131 + V932. (1) (a) For given (12,1), solve the consumer's utility maximization problem to nd the Mar- shallian demand function. Verify that his indirect utility function is I P2 P1 V ,I = 1/l1/. (p ) P1+P2[ P1 P2 (b) Construct the corresponding expenditure function e(p, u). Hint: use the fact that the expenditure function is the inverse of the indirect utility function. (c) Use Shephard's lemma to nd the Hicksian demand function h(p, u)
